Robert Kubica is continuing to make a strong recovery from his horrific rally accident earlier this year and expects to be on the pace when he finally returns to Formula One.

There is still no concrete date for Kubica's return, but his rehabilitation is progressing nicely and he intends to be back in an F1 car by next year at the latest. In a Q&A with fans on the Renault website, he revealed that he was recovering well.

"Mentally, no problem at all," he said when asked how he is feeling. "Physically, I am still a bit weak but my general condition is quite good. My weight has now returned to its normal level and for a few weeks I've been able to walk without help. All in all I feel pretty well."

He added: "I am satisfied with how things are proceeding. The improvement is in line with the expectations, and luckily there are no complications that could affect the recovery time. It is still too early to have a clear picture for the timing of my return but the important thing is the final outcome not the hurry."

Asked if he would return stronger, Kubica said: "Let's hope so! But in reality I don't see why, because I think I will be back exactly the way I was."

As for whether the accident affected his racing psyche, he added: "I don't have any memory of the accident, and I am just aware of the consequences it had. So, to me, it's as if it never happened."

Renault boss Eric Boullier recently said Kubica's race seat is open to him whenever he is ready, be it this year or next year, and Kubica is looking forward to his return to the team.

"I'm a Lotus Renault GP driver," he said. "Of course, I'm missing not being able to drive this season but I feel that my job in Enstone isn't finished yet."
